HT stands for “High Temperature”, as these are exactly the climatic conditions for which the mobile air conditioner PT 6500 HT has been designed.

It is not only in T3 climate zones that extreme outdoor temperatures prevail in the summertime. Even in previously more temperate climate zones, heat waves with very high temperatures are becoming more frequent. Conventional air-conditioners quickly reach their limits because their construction usually only allows them to operate as intended up to a maximum ambient temperature of +38 °C.

PT 6500 HT air conditioner – the mobile solution for high-temperature environments

Whereas the outside of the housing is structurally identical to its sister model PT 6500 S, all internal components of the PT 6500 HT's compressor refrigeration system are designed for use even in extreme summer conditions with temperatures up to +55 °C. In combination with the more powerful PT S+ heat exchanger, all components reliably generate a continuous flow of cooling air in environments with a temperature range of +7 to +55 °C.

The special cooling unit design of the PT 6500 HT ensures that this mobile air conditioner can provide maximum cooling performance even in extreme temperature conditions in T3 climate zones. And Duplex-Cooling even makes it possible to extend the application area to environments up to +60 °C.

Numerous detailed solutions prove the soundness and high quality of this professional air conditioner. For example we used super robust finned aluminium heat exchangers with thick-walled copper tubing. Additionally, the heat exchangers' rotary compressor was fitted on vibration absorbers to ensure the maximum lifetime. In addition, all internal components of the compression refrigeration system are designed for the use in high ambient temperatures up to +55 °C. Thus, a powerful centrifugal fan with radial flow ensures large-volume cold air circulation.

Once installed at the site of operation, the PT 6500 HT is ready for use within only a few minutes. For the power connection you simply require a 230 V outlet, and thanks to the connection set with quick-lock couplings, the connection to the external heat exchanger is established in no time. The connection line just contains circulating water mixed with glycol, so that there is no refrigerant loss when the PT 6500 HT is connected and disconnected. And by combining several connection sets the covered distance may be increased to maximally 30 metres, if required. This permits the cooling of remote, windowless rooms.

Typical applications:

• Personnel cooling in high-temperature environments such as steelworks, aluminium foundries, copper works
• Cooling of guest or staff areas in tropical climates
• Mobile cooling even under T3 climate zone conditions
• Reliable permanent cooling of computer rooms, measuring and control centres
